Find and install servers from a catalog.
Server Registries & Discovery is a free MCP Academy lesson on CoddyKit — lesson 3 of 4. You can read the complete lesson below for free — then practise it hands-on in the browser with a built-in code editor and a 24/7 AI tutor. It is part of the MCP Academy learning path, one of 4 lessons in the course, and your progress syncs across the web and the CoddyKit app.
Finding Servers to Use
You do not have to build every server yourself. Thousands already exist, so the real question becomes how to discover the good ones. 🔎
What a Registry Is
A registry is a catalog of published MCP servers. It lists each server with its name, description, and how to install and run it.
Like a Package Index
Think of a registry the way you think of PyPI for Python. It is a shared index where authors publish and users browse, search, and pull down servers.
Each Entry Carries Metadata
A listing includes metadata: the package name, version, transport, and the command needed to launch it. Hosts read this to wire the server up.
Install With a Command
Many servers ship as packages, so adding one is often a single command. The host then records it in config and starts it on demand.

A server runs code and reads data, so check it first. Review the source, the author, and the permissions it asks for before connecting it.
Pin Versions for Safety
An auto-updating server could change behavior overnight. Pin a specific version so what you tested is exactly what keeps running in production.
The Official Registry
The MCP project runs an open registry as a central place to publish and find servers, helping the ecosystem grow without one vendor in control.
Hosts Can Browse In-App
Some hosts build a browser right in, so you search a registry and add a server with a click. No hand-editing of config files required. 🖱️
Publishing Your Own
When your server is ready, you can publish it to a registry too, letting anyone discover and install it just as easily as you found theirs.
An Open Marketplace
Registries turn scattered servers into a searchable marketplace, so reaching a new capability is more about finding it than coding it. ✨
